摘要
以2005年至2009年陶瓷行业上市公司为样本,采用生产效率理论中的DEA-M指数方法测度技术效率和技术进步,发现陶瓷行业生产效率变动主要源于技术效率变化。在此基础上,本文基于面板数据随机效应模型,并引入相关控制变量的前提下,分别检验了企业价值与技术效率、技术进步之间的关联关系。结果表明,虽然二者对企业价值都存在显著、稳定的正向影响力,但技术进步作用有限。另外,检验结果也说明企业内部运营、内部治理结构与企业价值的关联作用并不明显。
Based on the sample of listed corporations in ceramic field from 2005 to 2009, by using DEA and Malmquist index to measure the technical efficiency and the technical progress, the paper finds out the fact that the main reason for the variation of efficiency lies in the technical efficiency. On this basis, the paper verifies the positive relation between the firm value and the technical efficiency by introducing the panel data random - effect model on the premise of adding some relative control variables. But there is a limited push from the technical progress. And the result also shows the fact that the relation between the inner operating system and the inner ruling structure is to some extent obscure.
